Interface Instance
- All Superinterfaces:
- Element, ModelElement, javax.jmi.reflect.RefBaseObject, javax.jmi.reflect.RefFeatured, javax.jmi.reflect.RefObject
- All Known Subinterfaces:
- ColumnValue, DataValue, Member, MemberValue, Object, Row
- public interface Instance
- extends ModelElement
The instance construct defines an entity to which a set of operations can
be applied and which has a state that stores the effects of the operations.
In the metamodel Instance is connected to a Classifier that declares its
structure and behavior. It has a set of attribute values matching the definition
of its Classifier. The set of attribute values implements the current state
of the Instance. Because Instance is an abstract class, all Instances are
either Object or DataValue instances.
The data content of an Instance
comprises one value for each attribute in its full descriptor (and nothing
more). The value must be consistent with the type of the attribute. An
instance must obey any constraints on the full descriptor of the Classifier
of
which it is an instance (including both explicit constraints and built-in
constraints such as multiplicity).
